I have been teaching my third grade students about quadrilaterals and came upon this blog entry. I LOVE the videos you made! Some of my students have been confused about the fact that some shapes can have a few names, so I plan on showing them the videos you created.

We know all of these quadrilaterals, but what happened to the trapezoid? As a sub-video, the trapezoid has one parallel side. Only two sides are equal to each other. Is that why it didn't make it to the video?

Our favorite quadrilateral is the SQUARE! She likes it because all of the angles are 90 degree angles, and they are all of the videos that you posted on your post. What quadrilateral do you like?
